The level of statistical significance is often expressed as a p -value between 0 and 1. The smaller the p-value, the stronger the evidence that you should reject the null ... WebNov 30, 2024 · P-value function. Because it’s difficult to see very small p-values in the graph, you can set the option log_yaxis = TRUE so that p-values (i.e. the y-axes) below the value set in cut_logyaxis will be plotted on a logarithmic scale. This will make it much easier to see small p-values but has the disadvantage of creating a “kink” in the p-value … charley\\u0027s sanford

"WebThe p -value for the given data will be determined by conducting the statistical test. This p -value is then compared to a pre-determined value alpha . Most commonly, an alpha value of 0.05 is used, but there is nothing magic about this value. If the p -value for the test is less than alpha , we reject the null hypothesis. " - P value from r value
